3D Keypoint Detection.
With the well-annotated 3D keypoints, HuMMan supports 3D keypoint detection. We employ popular 2D-to-3D lifting backbones [1]}, [2]} as single-frame and multi-frame baselines on HuMMan.
We experiment with different training and test settings to obtain the baseline results in Table  REF . First, in-domain training and testing on HuMMan are provided. The values are slightly higher than the same baselines on Human3.6M [3]} (on which FCN obtains MPJPE of 53.4 mm). Second, methods trained on HuMMan tend to generalize better than on Human3.6M. This may be attributed to HuMMan's diverse collection of subjects and actions.
